The nozzle is tapered in such a manner that its diameter decreases towards the discharge opening. The diameter of the nozzle at the entrance is larger than the length of the needle-like structures, and the diameter of the discharge opening is larger than the diameter of the needle-like structures and smaller than the length of the needle-like structures. By passing through the nozzle, the needle-like structures are aligned.
